A fast three-dimensional (3D) node localization algorithm in multipath for ultra-wideband (UWB) wireless sensor networks is developed.The algorithm employs a modified propagator method (MPM) for time delay estimation and then uses a marriage algorithm of 3D Hockey Accessories - Accessories Chan and Taylor for range-based multilateral localization a
This paper presents the results of an experimental and numerical study of the perforation of Armox 500T armoured steel.The plate perforation was performed with a pneumatic gun using three Bathroom Hooks types of penetrators.Sharp, spherical and blunt penetrators were used.The use of different geometries of penetrators causes the process of perforat
Augmented reality (AR) is an emerging technology that is applied in many fields.One of the limitations that still prevents AR to be even more widely used relates to the accessibility of devices.Indeed, the devices currently used are usually high end, expensive glasses or mobile devices.vSLAM (visual simultaneous localization and mapping) algorithms
